Neon Genesis Evangelion ((新世紀エヴァンゲリオン Shin Seiki Evangerion translated as "Gospel of a New Era") is an apocalyptic science fiction mecha anime created by the anime studio Gainax that was both ground-breaking and a huge critical success when it first aired in 1995.

The Evangelion fandom is often abbreviated into NGE, or Eva.

Two main ships emerge when looking at the fandoms: Kawoshin (Kaworu/Shinji) and Asushin (Asuka/Shinji). They don't get along very well. They're not the only ships though. Most center around Shinji: Rei, Misato, Kaji, or Toji are all potential pairings, though far smaller in fanworks. The Archive of Our Own shows that almost all fic there is Kawoshin. Examining FanFiction.Net reveals that other ships can be found in far greater numbers, though their fandom is very inactive.
